Up until this point, the Steam for Linux beta program was closed to the public, but making it available itsn't the only Steam-related news. Steam for Linux beta client bugs will be tracked through GitHub, which is a change from the use of forums in the closed version. Anyone can access the Steam for Linux repository with a free GitHub account in order to create, edit and track new issues as well as search others in the database.

There are a few other changes as well, such as the Steam installer package repository, and fixes to excessive CPU usage by the Steam client during Team Fortress 2 as well as overlay crash in Cubemen and better back navigation behavior/added discount behaviors in Big Picture.

For those who want to participate in the Steam for Linux beta program, download the most recent Steam Linux client or upgrade your current client to the latest version.
